The Pentagon has warned Congress that the long, drawn-out military campaign against Islamic State militants is just beginning and could expand to include modest numbers of U.S. forces fighting alongside Iraqi troops.

Secretary of Defense Chuck Hagel met with Albania's Minister of Defense Mimi Kodheli Monday at the Pentagon. Hagel thanked Minister Kodheli for her leadership in Albania's generous support to the government of Iraq through resupply donations.

Only a few weeks ago, Army leadership was planning to shrink its force to levels unseen since before World War II. But that was before Islamic State terrorists threatened to take over Iraq and Syria, before Russia invaded Ukraine and before the U.S. began deploying 4,000 troops to West Africa to help control the Ebola outbreak. Now the Army's Chief of Staff, Gen. Ray Odierno, suggests the Army and political leaders need to rethink their plans. He spoke with Emily Kopp at the Association of the Army Expo about the Army's next steps.
